"' 2 ,l EQUIPMENT-INDEX.

Specication of Letters Patent.

Patented Aug. 20, i918.

Application filed J une 27, 1917. Serial No. 177,241.

To all whom t may concern."

Be it known that I, JOHN H. VAN DnvnNTER, a citizen of the UnitedStates, residing at Yonkers, in the county of Westchester and State ofNew York, have invented certain new and useful Improvements inEquipment-Indexes, of which the following is a full, clear, and exactdescription.

The invention which constitutes the subject matter of this applicationrelates to an equipment index, the purpose of which is to provide in atechnical, trade or engineering publication of one or more pages, ameans by which each subscriber may form a perpetually up to date cardindex of equipment or other material and information.

Technical publications, especially in the machinery building field, makea practice of publishing for the benefit of their readers, a descriptionof each new machine or device put upon the market. The practiceheretofore has been to treat this, in the pages of these publications,as ordinary reading matter. No attempt, so far as I am aware, hastherefore been made to provide for clipping or otherwise severing thisinformation for a. card index system, as ordinarily the descriptionsvary in length, for example, from a short notice of a few lines toseveral pages.

The drawing accompanying this specification illustrates, somewhatdiagrammatically, one form which the device may take. In de.- tail thereference numeral lO designates one or more unit information sheets orareas contained in the journal in which it is published, and it will ofcourse be understood that the size and number of these sheets is amatter of choice of the publisher and that one sheet of standard sizemay be placed upon a page and the remainder of the page devoted to othermatter. The pages, upon which these sheets are contained, are preferablyscored, as indicated at l1, so that each sheet may readily be severed.Each sheet contains a unit description, that is condensed andstandardized as to space occupied, so that it may be cut out or severed,pasted upon a card of uniform size and tiled in a uniform card indexsystem. As a matter of practice. the material printed upon the re-,verse side of the sheets will be of such a nature as not to betechnical information7 or other important matter which would 0bviate thedesire of a reader to preserve it.

."With few exceptions, back copies of technical journals become lost ordestroyed, and hence the record of new machinery or other materialcapable of being condensed and standardized as to description is ofsmall value, as at present published. My invention enables theengineering, mechanical and other professions to have an available meansof preserving this material in small space, and keeping it perpetuallyup to date. And it will be seen that in providing a condensed andstandardized or unit description of each subject the material may be ledawa-y according to any desired classication. Of course it will beunderstood that in lieu of being scored, the areas or sheets7 maycontain perforations, guide lines or other indications for severing thesame from the magazine. And it will be further understood that theseareas or sheets may contain any desired information, such as anillustration of a machine, tool or device, the date of issue of saidpublication, the name of said machine, tool or device, the name andaddress of the maker of said machine, tool or device, the purpose,capacity and weight of said machine, the principal dimensions and floorspace occupied, etc.

What I claim is:

l. In a device of the class described, page of a publication of amagazine type, means for sizing and bounding one or more portions onsaid page less than its full size to cause them to conform in shape anddimensions to a card index file, informative indicia on each of saidportions relating to distinct subject-matter whereby the portions may beseparated on the boundary lines and each adapted to be led with itsappropriate subject-matter in the card index lile.

In a device of the class described, a page of a publication of amagazine type, means for sizing and bounding by markings one or moreportions of said page less than its full size to cause them to conformin shape and dimensions to a card index file, informativeindiciaconsisting of an illustration and accompanying description oneach of said portions rela-ting to distinct subject-matter whereby theportions may be sepamted cli the bcundai'y line and each adapted to befiled Wih its appropiinte subject matter ita the czid index Ele.

3. in a, device ci the dass described, :i page of i publication of amagazine type9 means for sizing md bounciing by weakened lines one oi"more pozions O' said page ess than its full size to cause tbem toconform in Shape and dimensicns tc si card index file.,
